ssss1 elaborates on the effect of formability parameters on tailor-welded blanks of lightweight materials. The product finds its maximum application in the automotive manufacturing industry. It is quite common that different materials with varying cross-sections are used based on the requirements in aerospace and automotive industries. To manage the herculean task of organizing this, researchers have enthusiastically proposed a tailor-made welded blanks (TWB) strategy, and in many automotive industries this technique has been adopted. This chapter suggests testing the formability of tailor-welded blanks with various light alloy sheets used in the aerospace and automotive industries. An overall review of various parameters that affect the formability of tailor-welded blanks is presented in this chapter, so that other investigators can rely on the same for more critical observations in this field.

ssss1, the last chapter of this section, presents the various ways of optimizing a vehicle body, such as shape optimization for aerodynamics and aesthetics, and weight of materials to be used for fuel efficiency, material conservation, recyclability and others. This chapter considers a product called “B-pillar”, one of the critical structural support members of sedan cars. They have replaced the existing material with a composite, mainly to overcome the stress developed due to the system as it is a structural member and to safeguard the occupant in the case of a side crash. Different mechanical properties such as tensile, compression and bending strength, as well as water absorption, were measured. The model of the sedan car B-pillar panel developed was analyzed for impact and crush simulation. It concluded that a composite can be used for the outer panel of B-pillar, which results in reduced vehicle weight and fuel consumption and increased energy absorption.
